The expression below represents Javier's pay for the week: 14w + 56 What does the coefficient of the expression represent? Kyle's pay for the week. The pay for each window installed. The number of windows Javier installed. The number of windows Kyle installed.

Answer 1

For this case, the first thing we must do is define variables.

We have then:

w: number of windows installed.

For the payment of Javier this week we have the following expression:

14w + 56

This function is a linear function.

The cutoff point with the y-axis represents the extra money for installing doors.

The slope of the line for this case represents the payment for each installed window.

Answer:

the coefficient of the expression represents:

The pay for each window installed
